Kids need to learn that their meat doesn't come from the grocery store. Gordon Ramsay did something similar with his kids (who were much younger but I don't think he killed/skinned them in their presence) on F-Word on BBCA. I'm sure they see worse on TV and in the movie theater.
My grandfather had a cattle ranch he bought when he retired so I knew that the cute cow I liked might some day be on the table - and I've never even THOUGHT about being a vegetarian.
